An application is needed for the following purpose:
Our firm wants to advertise through the "Personal messages" of our users in Windows Live messenger/ Msn messenger. We will offer them a discount in our products, if they put OUR SLOGAN as they personal message. To track if this is true, we can ask them to ADD our address in their contact list, so we can see if they actually have our slogan for the agreed time. As there will be an important number of users doing this (10000+ a day) we need it to be automated. We can offer two options, for example: if they leave the message for 24 hours, they get 10% off, if they leave it for 72 hours, they get 25% off.
Users who have accomplished the agreed timeframe with our slogan as their personal message, should automatically receive an email with a link to print their discount coupon. This link must be good for one time use only.
